IMPROVEMENT IN WELL-TUBES.l

TO ALL'WHOM IT MAYCONCERN:

Be it known that I, M. L. BASSETT, of Westl Haven, in the county of NewHaven, and State of Connecticut, have invented a new Improvement inWell-Tubes; and I do hereby declare the following, when taken inconnection with the accompanying drawings, and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure l, a. side view.

. Figure 2, a vertical centralisection. Y

This invention relates to that class of wells which are formed hylforcing into the earth a metal tube, perfo. rated at its lower end, sothat water will enter the tube, when it has been forced down to therequired depth, and the applying of an ordinary pump to the tube. Thetube serves as the well, and avoids the necessity of l digging.

In the' use of this class of wells a great difficulty is experienced,through the liability of sand to iow into* the tube, and be drawn upbythe pump, to the great injury ot' the pump. 'lhe object of thisinvention is to overcome this diiculty, and consists in the employmentof a filter and dripuinv immediate connection with the tube, and betweenthat and the pump, so that the drip will receive the sand, and the clearwater pass onto the pump.

To enable others to construct and use my improvementLI will proceed todescribethe same asz'illustrated in the accompanying drawings. A`

A is the well-tube, of any common or known construction. -B is a.tube,to which the pump is attached in the usual manner; the tube B beingattached to the tube A by meansnoi a T, C, and elbow D, as seen in thedrawings. Within -the tube B is'arranged a conical strainer, E, fillingthe t-ube at the lower end, so that the water must pass therethrough onits vway to the pump, and this strainer is best made from wire-gauze, ormay be from perforated sheet metal. From the T, C, downward, extends atube, F, and to its lower end is fitted a cap, G, having an openingthrough its bottom, stopped by a screw, H, or other convenient device.

The operation of this arrangement is as follows: ,The water is drawn upthrough the tube B in the usual manner,l passing. through the strainerE. The sand, which may be in the-water drawn up to this point, and abovethe drip-tube F, sinks into the drip, and settles to the bottom of thetube F, or, prevented from further progress by the strainer'E, it thensettles into the drip-tube F, and ymay be removed therefrom by takingout the screw II or removing the cap.

Having thus fully described my invention, what I claim as new'anduseful, and desire to secure by Letters Patent, is--f/'I The arrangementdescribed of the drip-tube F and well-tube A with the tube B, whenthe'said tube B is provided with a conical strainer or lter E,substantially as herein set forth.

M. L. BASSETT.
